The Foot and Ankle Online Journal 13 (2): 3

Achilles tendon rupture is a debilitating injury with a protracted and sometimes incomplete recovery. The surgical method of Achilles tendon repair, like open repair with or without augmentation, has a higher complication rate like delayed tendon healing (since paratenon integrity is destroyed in open repair technique which delays or hampers the tendon healing). Wound healing problems like suture granuloma, deep infection, skin edge necrosis, superficial dehiscence, pressure ulcer, and blisters may occur. Here we developed a newer hybrid technique (open exposures of the tendon and percutaneous tenodesis through calcaneum) for Achilles tendon repair to minimize the complications and enhance the tendon healing. Excellent results were observed with this hybrid technique.

The Achilles tendon is the most frequently ruptured tendon in the human body [1]. The mean age of presentation is 35 years with a male:female ratio of 20:1 [2,3].

The commonest site of rupture is in a region 3 to 6 cm above the calcaneus which corresponds to a watershed region of poor vascularisation[4]. Perfusion in this region is further compromised during stretching and contraction [5,6]. With increasing age there is decreased collagen-cross linking and weakening of the tensile strength of the tendon. Maffulli, et al., [7] and Järvinen, et al., [8] histologically observed significant collagen degeneration in patients with Achilles tendon rupture. Ruptured Achilles tendons have histologically demonstrated collagen degeneration with a greater content of collagen III and less collagen I [8].

Both oral and intratendinous injection of steroids have been implicated in spontaneous tendon rupture [9]. Other risk factors for rupture of the Achilles tendon include steroid therapy, hypercholesterolemia, gout, rheumatoid arthritis, long-term dialysis, and renal transplantation [10-14].

Surgical treatment, like the open repair technique, is associated with an increased incidence of postoperative complications, such as skin-tendon adhesions, infection, delayed healing of the surgical wound, sural nerve lesion, and suture granulomas [15].

Percutaneous repair, first described by Ma and Griffith [16], seems to bridge the gap by combining the advantages of both methods [17,18]. It is associated with a lower complication rate compared to open operative repair [15] but it may be associated with a higher risk of re-rupture and sural nerve injury [19]. However, several researchers have reported the absence of re-ruptures and nerve lesions [20].

Material and methods

A consecutive series of Achilles tendon rupture in 12 patients, occurring between 2 to 4 cm proximal to the calcaneus tuberosity, were treated by a hybrid technique (open exposures of the tendon and percutaneous tenodesis through the calcaneus). In all cases, the diagnosis was based mainly on history and clinical examination (functional impairments, palpation of the gap, and the Thompson test) and confirmed by ultrasound examination and MRI.  All patients were evaluated on follow-up.


The patient typically presents with pain, inability to bear weight and a history of a clear popping sensation or sound after an episode of activity during which they sustain a forced dorsiflexion of the ankle. The injury can also be sustained during eccentric contraction. The patient frequently describes the sensation of being kicked, shot or even bitten on the back of the heel. Acute Achilles tendon rupture can readily be detected on physical examination. Plantar flexion of the foot is understandably weak [16]. The Achilles tendon is best examined with the patient kneeling and the feet hanging over the edge of the chair. In this position, soft tissues hang off the Achilles tendon like a tent ridge pole and defects can be readily visualized (Figure 1). There is frequently a visible defect in the Achilles tendon. This is accompanied by swelling due to peritendinous hematoma.

Operative technique

The patient was placed in a prone position under general, spinal or peripheral nerve block anesthesia with the knees slightly flexed and a pneumatic tourniquet placed around the proximal part of the thigh. Before starting the procedure, the rupture and the diastasis (gap) were localized. The procedure is illustrated and described in detail in Figures 2-18.

The choice of suture material has important implications in tendon repair. Here we demonstrated excellent tendon healing results. Adverse surgical outcomes can be avoided by selection of the suitable suture materials for appropriate indication. Risks of Achilles tendon repair with open technique with or without augmentation include:

  • Excess bleeding
  • Nerve damage
  • Deep Infection
  • Blood clot
  • Wound healing problems like suture granuloma, skin edge necrosis, superficial dehiscence, pressure ulcer, blister.
  • Calf weakness


Hybrid technique (open exposures of the tendon and percutaneous tenodesis through calcaneus) of Achilles tendon repair with single ethibond suture has obtained better results in terms of tendon width , muscle mass and strength recovery of plantar flexion and patient satisfaction. As single Ethibond suture is used for tendon repair it decreases chances of postoperative infection. significantly good results were found in terms of clinical outcomes. Better outcomes found with Achilles Tendon Rupture Score.
